South Pacific Metals Corp. Reports Rock Chip Assays with High-Grade Copper up to 21.2% at Ontenu NE
None
On November 11, 2025, South Pacific Metals Corp. (SPMC) announced high-grade copper and gold assay results from rock chip sampling at the Ontenu NE prospect, part of its Osena Project in Papua New Guinea. Key highlights include selective samples grading up to 21.2% copper (Cu) and 9.34 grams per tonne (g/t) gold (Au).
The CEO, Timo Jauristo, stated that these copper results complement previously released high-grade gold results and are characteristic of intermediate sulfidation epithermal deposits, similar in style to the nearby K92 Mining operation. The release confirms that the company has recently commenced drilling in the southern part of Ontenu NE.
The news is positive as it confirms the presence of high-grade copper and gold mineralization at the surface of the Ontenu NE prospect, reinforcing the rationale for the ongoing drill program. However, the impact is routine and not material. These are selective grab samples, which are inherently not representative of the overall grade of a deposit. They are a tool to identify targets for drilling.
The company has been consistently releasing positive surface sampling results throughout the year, which successfully built anticipation for a drill program. The truly material news was the announcement on October 30, 2025, that the maiden 1,500-metre drill program had commenced.
This November 11th release serves to maintain market interest while the company awaits the first drill core assays. It meets expectations based on prior surface work but does not provide new, game-changing information. The value of the company now hinges not on more surface samples, but on demonstrating that this surface mineralization extends to depth with economic widths and grades, which only drilling can prove.
The progression of news has been logical: - Early 2025: Secured $6.3 million in financing. - Mid-2025: Strengthened management (appointed experienced CEO Timo Jauristo), acquired a drill rig, and conducted systematic surface exploration at Osena and Anga, consistently reporting encouraging surface grab sample results. - Oct 30, 2025: Achieved the key milestone of commencing the maiden drill program at Ontenu NE. - Nov 11, 2025: Released more positive surface samples from the area being drilled.
The company has successfully executed its plan to get the drill turning. This latest news is simply another data point supporting that plan, not a result of it.
South Pacific Metals is a junior exploration company focused on gold and copper projects in Papua New Guinea (PNG). The company holds a large land package of over 3,100 km² across four projects: Osena, Anga, Kili Teke, and May River. The properties are strategically located adjacent to major producers like K92 Mining and Barrick/Zijin.
The current flagship project is the Osena Project, specifically the Ontenu prospect. Osena is located adjacent to K92 Mining's high-grade Kainantu Gold Mine. After a year of successful surface exploration that identified multiple gold and copper anomalies, the company commenced its maiden drill program at the Ontenu NE target in late October 2025. The company also holds the Kili Teke project, which has a historical inferred resource of 1.81M oz Au and 802,000 t Cu.
